DS got his first bottle feeds this week and did great. However they've put a hold on them because of his high respiratory rate due to some congestion he's having. The NICU is using regular, brown Enfamil nipples and he did fine. I'm wondering if we'll be able to get by with just a regular, cheap bottle and nipple since we know he'll take it. Or should we go for something nicer like Dr. Brown's? Any thoughts and advice would be appreciated!
